Left tail light, left blinker and brake light not working

I have a motorhome 2018 Coachmen Freelander 22qb. I was trying to hook up my towable car and I must have put the cable the wrong way. I had the RV running at the time. I probably burnt something. So I checked that fuses on both the engine block and under the seat and the fuses are okay. Ever since then, my left tail light is not working. The only thing that works on the left light is the reverse light when put in reverse. So my brake light and my left turn signal and also when turning the lights on do not turn the tail light on at all.
